Hey David, It looks like you're mixing and matching some stuff between gem5 versions here. I'm pretty sure you took that 'x86-npb-benchmarks.py' script from the the repo checkout out fo v21.2, but you're running it on gem5 v21.1. I suspect that's the problem. If you want to run this script you'll need to checkout the latest version of gem5:
``` git checkout stable && git pull ``` Delete the build directory and recompile. This will get you gem5 v21.2.1 which should work with the x86-npb-benchmark.py script -- Dr. Bobby R.
